What should I do if I bought a ticket at Ticketmaster ticket centres?

From July 15 you can return your tickets in person to the centre where you purchased them and complete the refund form available there. You should make a note of the show date and seat details and retain the left-hand portion of the refund form. A full refund will be processed by bank transfer within 21 days of receipt.

If you purchased tickets from News & Deli, Dundalk; Fassaught Stores Cabra, Dublin; Whites, Wexford; the Irish Shop, Ennis or Cusack Park, Ennis, these are no longer affiliated with Ticket-master so you should apply for a refund via any other Ticketmaster ticket centre or by post.

What happens now that Brooks is calling for the concerts to go ahead?

Tickets purchased from ticket centres can also be returned along with a refund form available via the Garth Brooks FAQ page on ticketmaster.ie/gbrefunds.

Please make a note of the show date, seat number, and keep the left-hand portion of the refund form for your records. A refund will be processed by bank transfer within 21 days of receipt.

What should I do if I booked a hotel for the concert?

Most hotels allow cancellations free of charge if they're well in advance of the booked stay but this can depend on the contract with the hotel or a booking site.

The Irish Hotels Federation has said it expects most hotels will be flexible about allowing cancellations even for those cases where the customer booked a prepay rate that doesn't permit them.

What if I booked a flight from abroad for the concerts?

Airlines do not issue refunds or permit changes on most bookings. The most you can probably hope for is to get back taxes and charges if you don't use the ticket, minus an administration fee.
